“韩国小姐”的脸到底有多相似?

本文作者:小行踪<p><b>编辑的话:</b>2013年“韩国小姐”选美大赛开始之后,最先曝光出的20位佳丽面容之酷似,让人们惊叹不已。我们在黄嘉斌的个人博客上看到了这篇有趣的 分析文章(英文)。在得到翻译授权后,死理性派将本文编译发布,以飨读者。<p>(原作者/黄嘉斌 译/小行踪)前一阵,一张集合了20 位“韩国小姐”选美大赛大邱区选手的GIF图(见下)广为流传,世人纷纷震惊于韩国整容技术的高度一致性。有网友称“韩国整容界的混乱终于在这一张脸上体现出来了”。那么,这20位韩国小姐的脸到底有多相似?让我们用科学的方法来揭开谜底。<p>首先,放出20位佳丽集合图,并对她们进行编号(第一列从上往下依次为1-4号,第二列为5-8号 …

肢体语言的神话和现实

本文作者:亚得里亚海上的猪<p>(文/Caroline Williams)汤姆·克鲁斯和凯蒂·赫尔姆斯在2012年宣布离婚时,小报记者纷纷激动地表示,自己早就料到了这一天。报纸上的头条叫嚣着“肢体语言说明一切”,底下就是赫尔姆斯蹙着眉头、拉长胳膊牵着克鲁斯的照片——“真别扭”!同样是2012年,奥巴马在第一场大选辩论中输给共和党的罗姆尼时,也有一些评论家将这场失败归咎于他那“负能量满满”的肢体语言,以及他频频俯视瘪嘴的习惯,这些动作让他显得“倦怠而且准备不足”。<p>这样的洞见在流行文化里俯拾皆是。毕竟,猜测公众人物的内心是件有意思的事。然而,任何有点怀疑精神或者逻辑头脑的人,都无法对一个显然的事实视而不 …

给人惊喜,但不要太多:不可不知的消费者心理学

本文作者:PanSci<p>当有朋友生日想在网络上找间餐厅好好庆祝一番,此时你发现了两家点评差不多的餐厅,分别提供了不同的优惠:<b>“生日寿星用餐我们将赠送神秘小礼物”</b> <b>或是</b> <b>“生日寿星我们将赠送特调红茶一杯”。</b>此时你会选择去哪家餐厅呢?<p>在上述的问题中,其实隐含了一个影响购买的重要因素——“不确定性” (uncertainty)。<p>从传统心理学的观点来看,当购买决策有着不确定性时,人们的购买欲会下降,因为不确定性会使人焦虑不安,难以作出决定。“分离效应 ”(Disjunction Effect)指出:人们总是想等待信息被披露后再做决定。<p>但也有学者发现,其实<b>不确定性有时反而会增加人们的购买欲望</b>。就像买彩票和抽奖 …

大数据时代,我们还有隐私吗?

本文作者:zhanghuicuc<p>随着数字信息技术的不断发展,“网络匿名”有可能会变成“数学上不可能”的事。<p>1995年,欧盟出台的隐私法例将“个人资料”定义为可以直接或间接识别一个人的信息。很显然,当时立法者考虑的是那些带有身份标识号的文件资料之类的东西,这些标识号就好像人的姓名,而立法者们希望它们可以得到保护。<p>如今,“个人资料”这一定义所包含的内容已经远远超出当年那些立法官员的想象,甚至可以轻易地超过18年前他们通过这项法例时整个世界的数据量。<p>来看看到底发生了什么。首先,这个世界每年所创造的数据量在以指数形式增长,去年,这一数字则达到了2.8ZB(1ZB =10244GB),听起来就很可怕的数 …

3D成像,也可以有简单便宜的方法了!

本文作者:小行踪<p>我们的视网膜、普通的相机所捕捉的都是二维图像,如果捕捉一个物体的三维(3D)立体画面就需要做进一步的处理。尽管现在已经有不少可做到这一点的技术(比如全息成像技术、运动捕捉技术等等),但它们的成本往往很高,而且需要大量的镜头和激光发射装置等昂贵的光学元件。另外,这些技术可能只适用于特定波段的光,这也限制了它们的使用。而现在,科学家们已经研发出了一种更加简单和廉价的创建3D图像的方法。<p>来自英国格拉斯哥大学的孙宝清及其同事研发出了一种无需镜头和复杂设备便可重建物体3D图像的的方法。通过给一个3D物体(此例中是一个人头模型)进行照明,并用一种被称为“单像素检测器”的微小光检测器从不同的 …
